local only

nanomem runs on your own machine — the client starts it, so there is no endpoint to ping. 192 installs a week from pypi. Last commit 23 Sep 2026.

Memory that knows when a remembered fact has been replaced, not just when it was written.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

        out = subprocess.check_output(["ps", "-o", "rss=", "-p", str(os.getpid())],
    return os.path.join(CACHE, corpus)
    for root, _d, files in os.walk(p):
  "per_question_gold_hits_B1": "12122112111211222202211222212221212212111122222221122011211222022212111222212222122211122112212212221021212122212211022222212221222212122222112222210222122122112111222211222221222122222221211121111212202211122210122022211202221221221221122211211221…

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add nanomem -- uvx nanomem
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "nanomem": {
      "command": "uvx",
      "args": [
        "nanomem"
      ]
    }
  }
}
~/.codex/config.toml
[mcp_servers.nanomem]
command = "uvx"
args = ["nanomem"]
.cursor/mcp.json
{
  "mcpServers": {
    "nanomem": {
      "command": "uvx",
      "args": [
        "nanomem"
      ]
    }

    }
  }
}

Optional settings from the registry entry, left out of the block above: NANOMEM_VAULT (Path to the memory vault file. Defaults to ~/.nanomem/memory.dat), NANOMEM_PASSWORD (Passphrase to encrypt the vault at rest. Leave UNSET for a plaintext vault; setting it to an empty string is refused rather than silently producing one).

nanomem — questions

Answers built from our own checks of this server.

Why is there no uptime for nanomem?
nanomem runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package nanomem was installed 192 times last week.
How do I connect nanomem?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls nanomem straight from pypi; nothing to host, nothing to sign up for.
How many people use nanomem?
The pypi package nanomem was installed 192 times in the last week. Week over week that is +63%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is nanomem open source?
Yes — it is published under the Apache-2.0 licence, written in Python and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
